             Summary: if NMClientAsync stopContainer failed because of 
IOException,  there's no change to stopContainer again
                 Key: YARN-3327
             Project: Hadoop YARN
          Issue Type: Bug
          Components: api, client
    Affects Versions: 2.6.0
            Reporter: sandflee

In AM, I use NMClientAsync to control containers, when I use stopContainer to 
kill container ,IOException happens, then If I stopContainer again, nothing 
happens, because container Managed by NMClientAsync came to FAILED state.
In my opinion, IOException just means temporary error,it shouldn't came to 
FAILED state especially when NM Restart is enabled。
